New framework creates physics-constrained AI models for turbulent systems

Researchers have developed a new framework for creating data-driven reduced-order models of turbulent dynamical systems. This framework utilizes neural networks to ensure physics constraints, specifically energy conservation, leading to stable models. The models are validated using the fluctuation-dissipation theorem, allowing them to predict responses to external perturbations based solely on unperturbed data. The methodology was successfully applied to idealized geophysical turbulence models and the complex dynamics of the El Niño-Southern Oscillation (ENSO), demonstrating its capability to probe causal mechanisms in realistic systems.
